Objective To explore the safety of Yttrium-90 resin microsphere selective internal radiation therapy (⁹⁰Y-SIRT) on malignant liver tumors. Methods A retrospective analysis was conducted on 64 patients with malignant liver tumors who underwent ⁹⁰Y-SIRT from February 2023 to November 2024 at Weifang People’s Hospital. The clinical characteristics of the patients and the occurrence of adverse reactions after treatment were analyzed to assess the safety of ⁹⁰Y-SIRT. Results Among the 64 patients, there were 52 males (81.25%) and 12 females (18.75%); the average age was (56.29±11.08) years. Seven patients (10.94%) had tumors with maximum diameter of less than 5 cm, 38 patients (59.38%) had tumors with maximum diameter of 5-10 cm, and 19 patients (29.68%) had tumors with maximum diameter of greater than 10 cm. There were 47 cases (73.44%) of solitary lesions and 17 cases (26.56%) of multiple lesions; 53 cases (82.81%) were primary liver cancers and 11 cases (17.19%) were metastatic liver cancers. Of the 64 patients, 63 successfully completed the Technetium-99m macroaggregated albumin (^99mTc-MAA) perfusion test and received the ⁹⁰Y-SIRT; one patient received ⁹⁰Y-SIRT after the second ^99mTc-MAA perfusion test due to a work error. The most common adverse reactions included grade 1 alanine aminotransferase (ALT) elevation in 26 cases (40.62%) and grade 2 in 2 cases (9.37%), grade 1 aspartate aminotransferase (AST) elevation in 27 cases (42.18%) and grade 2 in 7 cases (10.93%); grade 1 nausea in 17 cases (26.56%) and grade 2 in 6 cases (9.37%); grade 1 abdominal pain in 12 cases (18.75%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%); grade 1 vomiting in 11 cases (17.18%), grade 2 in 5 cases (7.81%), and grade 3 in 1 case (1.56%). Conclusion The adverse reactions of ⁹⁰Y-SIRT for treating malignant liver tumors are mild, indicating good safety.

Ferroptosis of chondrocytes is a significant contributor to osteoarthritis (OA), for which there is still a lack of safe and effective therapeutic drugs targeting ferroptosis. Here, we screen for anti-ferroptotic drugs in Food and Drug Administration (FDA)-approved drug library via a high-throughput manner in chondrocytes. We identified a group of FDA-approved anti-ferroptotic drugs, among which vitamin K showed the most powerful protective effect. Further study demonstrated that vitamin K effectively inhibited ferroptosis and alleviated the extracellular matrix (ECM) degradation in chondrocytes. Intra-articular injection of vitamin K inhibited ferroptosis and alleviated OA phenotype in destabilization of the medial meniscus (DMM) mouse model. Mechanistically, transcriptome sequencing and knockdown experiments revealed that the anti-ferroptotic effects of vitamin K depended on growth arrest-specific 6 (Gas6). Furthermore, exogenous expression of Gas6 was found to inhibit ferroptosis through the AXL receptor tyrosine kinase (AXL)/phosphatidylinositol 3-kinase (PI3K)/AKT serine/threonine kinase (AKT) axis. Together, we demonstrate that vitamin K inhibits ferroptosis and alleviates OA progression via enhancing Gas6 expression and its downstream pathway of AXL/PI3K/AKT axis, indicating vitamin K as well as Gas6 to serve as a potential therapeutic target for OA and other ferroptosis-related diseases.

Bone growth and development is a major determinant of height.Height development in children is the result of the proliferation and endochondral ossification of growth plate chondrocytes located at the ends of long bones and vertebrae.Short stature，also known as dwarfism，means that a child's height is less than two standard deviations of the normal interval for children of the same race，region，and sex，or below the 3rd percentile of the normal child growth curve，which is a common problem in pediatric endocrinology.A variety of physiological regulatory pathways involving growth plate and long bone development have been reported，and related gene defects may be the key mechanisms leading to growth disorders and abnormal skeletal development in children.The ACAN gene，which is associated with osteochondral dysplasia，has garnered widespread attention from numerous scholars in recent years.This article reviews the genetic etiology，clinical phenotype，treatment and management of short stature caused by ACAN gene mutation in children.

Helicobacter pylori(H.pylori)infection triggers gastric mucosal inflammatory responses and spasmolytic polypeptide-expressing metaplasia(SPEM).These pathological conditions can escalate the severity of chronic gas-tritis,gastric ulcers and even cause gastric cancer.SPEM is frequently viewed as an early sign of gastric mucosal injury and the onset of carcinogenesis.A comprehensive analysis of the genesis and molecular regulation of SPEM cells in the context of H.pylori infection further has enlightened the pathogenesis of gastric mucosal diseases and provide new ideas and targets for diagnosing and treatment of H.pylori-related gastric mucosal diseases.This paper reviews a variety of molecular biomarkers associated with SPEM,encompassing TFF2,CD44v9,and AQP5,and delineates their pivotal regulatory functions in H.pylori infection and SPEM.This paper also reviews the origination of SPEM cells and pertinent molecular regulatory mechanisms.

Corneal lymphangiogenesis plays a crucial role in ocular diseases. Normally, the cornea lacks blood vessels and lymph vessels, which are essential for maintaining transparency and function of cornea. However, certain diseases or injuries will prompt angiogenesis and lymphangiogenesis in cornea, thus disrupting the structure and function of cornea. Although various drugs targeting corneal angiogenesis have been applied in clinical practice, there is still a gap in medications targeting corneal lymphangiogenesis. Therefore, this review will introduce the factors related to corneal lymphangiogenesis, introduce related ocular diseases, and analyze the current treatment status, which will provide more options and possibilities for the treatment of lymphangiogenesis in ocular diseases and provide guidance for future research and drug development.

【Objective】 To investigate the development of adaptability in children aged 2 - 6, and to explore its influencing factors, so as to provide reference for promoting the development of adaptability in young children. 【Methods】 Data were from the National Nutrition and Health Systematic Survey for Children in China, and 3 319 children aged 2 - 6 and their parents from 28 sites across 14 provinces were recruited in this study.The Development Scale for Children Aged 0 - 6 years (WS/T 580-2017) was used to measure the developmental quotient of children′s adaptive ability, and a survey questionnaire was used to collect relevant information about children and their parents. 【Results】 Among 3 319 children aged 2 - 6, the proportion of slightly low or low level of adaptability, moderate adaptability development, good and excellent adaptability development was 7.68%,66.25% and 26.06%, respectively.The proportion of children aged 5 - 6 with good and excellent adaptability was lower in 3-year-old and 4-year-old groups (χ²=59.29, P<0.05).Multiple stepwise linear regression showed that children′s gender (β=0.06), gestational age of birth (β=-0.05), only child (β=-0.04), left-behind child (β=-0.04), the main caregiver (β=-0.06), and the education level of parents (β=0.09, 0.10), whether parents actively pay attention to children′s emotions (β=-0.06) and whether children play with homemade toys (β=-0.04) were the influencing factors of children′s adaptive development quotient.Girls, full-term children, only children, non-left-behind children, children with parents as main caregivers, parents with a high level of education, parents who often take the initiative to pay attention to children′s emotions, and children who play with homemade toys had a higher level of adaptability development quotient. 【Conclusions】 The development level of adaptability in children aged 2 - 6 in China is mostly above the average level and is related to multiple factors.Targeted intervention work can be carried out on relevant factors in order to promote the development of children′s adaptability.

Objective To analyze the relationship of the volume of 87 brain regions with postnatal age and neurobehavior in full-term neonates.Methods A total of 75 full-term newborns[gestational age(39.38±1.22)weeks;male/female(51/24);postnatal age(11.11±6.67)days]without abnormalities on brain MRI(three-dimensional T1-weighted imaging,3D T1WI)at our hospital between November 2010 and September 2017 were retrospectively included.Based on the template of 87 brain regions,the neonatal brains were divided into 87 brain regions and their volumes were calculated by using V-shape Bottleneck network(VB-Net)deep learning segmentation technique,Pearson partial correlation and regression analysis were used to explore the relationship of the volume of each brain region with postnatal age and neurobehavioral scores.Results After adjusting for gestational age,birth weight,head circumference,body length and sex,66.7％of the regional brain volumes(58/87 brain regions)significantly increased with the postnatal age(correlation coefficient r:0.2-0.7,P＜0.05).The volumes of gray matter in bilateral lentiform nucleus,left caudate nucleus,right occipital lobe,right inferior temporal lobe,and bilateral anterior temporal lobe strongly correlated with the postnatal age(r＞0.50,P＜0.05).The gray matter volume of the right occipital lobe linearly increased with age(slope:100.67),and was positively correlated with behavioral scores(r=0.324,P＜0.01).Conclusion Most of regional brain volumes increase with the postnatal age during the neonatal period,and the fastest growth occurs in primary sensorimotor-related brain regions,presenting the spatial heterogeneity.Partial brain region grows with the development of behavioral ability.

TCM believes that spleen deficiency is the root cause of emotional abnormalities in chronic fatigue syndrome (CFS), and clinical treatment often involves the heart, liver and kidney. TCM therapy has a significant efficacy in CFS emotional abnormalities. It is mostly treated with oral administration of TCM, acupuncture, moxibustion and massage therapy. It may play a therapeutic role by improving oxidative stress and immune inflammation, regulating nerve-endocrine, controlling energy metabolism and other ways. It is suggested to establish the syndrome differentiation standard of CFS emotional abnormality in the future, so as to improve the accuracy of syndrome differentiation and treatment; form a perfect treatment guide or expert consensus to guide the standardized application of various internal and external treatment methods; explore objective indicators based on the pathogenesis, and focus on the morphological and functional changes of disease target brain regions with the help of neuroimaging techniques, so as to improve the diagnosis and prognosis evaluation of CFS; based on the guidance of TCM theory, improve the CFS emotional abnormal animal modeling method.

Objective Investigate the expression level and clinical significance of microRNA-223-3p(miR-223-3p)in the serum of pregnant women with preterm premature rupture of membranes(PPROM).Methods A total of 91 pregnant women who underwent cesarean delivery at the Xuzhou Maternal and Child Health Hospital affiliated with Xuzhou Medical University between April and September 2023 were selected for the study.This included 60 cases of PPROM and 31 cases of term normal pregnant women as the research subjects.The study group was divided based on the pathological results of the membranes into:PPROM group without histological chorioamnionitis(HCA)(PPROM group,n = 37),and PPROM group with HCA(PPROM+HCA group,n = 23).Serum samples from pregnant women were collected before hospital treatment,and the expression level of miR-223-3p in the serum was detected by quantitative real-time PCR(qRT-PCR).The levels of inflammatory factors such as IL-1β,IL-6,IL-8,and TNF-α in the serum were measured by enzyme-linked immunosorbent assay(ELISA).Results The expression level of miR-223-3p in the serum of the PPROM+HCA group was significantly higher than that of the PPROM group and the normal group(P＜0.05).The expression levels of IL-1β,IL-6,IL-8,and TNF-α in the serum of the PPROM+HCA group were also significantly higher than those of the PPROM group and the normal group(P＜0.05).There was a positive correlation between the expression level of miR-223-3p in the serum of the PPROM+HCA group and the expression levels of IL-1β,IL-6,IL-8,and TNF-α(r = 0.553,0.505,0438,0.656,P＜0.05).Conclusion The upregulation of miR-223-3p in the serum of pregnant women with PPROM+HCA is associated with the severity of inflammation in PPROM.

OBJECTIVE To investigate the relationship between metformin and sarcopenia-related traits. METHODS Based on the data from publicly genome-wide association study-related databases， using single nucleotide polymorphisms strongly associated with metformin as instrumental variables， the two-sample Mendelian randomization （MR） analysis methods [inverse variance weighting （IVW） method， MR-Egger regression method and weighted median estimator method] were employed to investigate the relationship between metformin and three sarcopenia-related traits （low grip strength， muscle mass and walking speed）. Cochran’s Q test was used to assess heterogeneity， MR-Egger intercept test was used to detect horizontal pleiotropy， and leave-one-out analysis was performed for sensitivity analysis. RESULTS The results of IVW method showed that metformin use was significantly associated with an increased risk of low grip strength （β＝1.550， 95%CI was 0.389-2.711， P＝0.009） and reduced limb muscle mass （right leg lean body mass： β＝－0.665， 95%CI was －1.018-－0.312， P＜0.001； left leg lean body mass： β＝－0.710， 95%CI was －1.049-－0.371，P＜0.001； right arm lean body mass： β＝－0.471， 95%CI was －0.890-－0.053， P＝0.027； left arm lean body mass： β＝－0.463， 95%CI was －0.865-－0.061， P＝0.024），but was not associated with walking speed. The results or causal effects of the other two methods are consistent with it. The Cochran’s Q test indicated some degree of heterogeneity in the result of this study. No horizontal pleiotropy was detected by the MR-Egger intercept test. The sensitivity analysis suggested that the results of this study were stable. CONCLUSIONS Metformin may increase the risk of sarcopenia.
